| Abstract | This dataset contains 2778 vertical profiles of water quality in Tsukumo Bay, Japan, collected in 2021, no data are available for December. The data were collected using a JFE Advantech AAQ-RINKO175 direct-reading water quality meter at seven fixed stations at northwest of Hourai Island. Measurements were taken monthly from the surface to the bottom, recording depth, Seawater Temperature [℃], Salinity, Conductivity [mS/cm], EC25 [μS/cm], Density [kg/m3], σＴ, Chl-Flu. [ppb], Chl-a [μg/l], Turbidity [FTU], DO [%], DO [mg/l] and Photon [μmol/(m2*s)]. The raw data were processed using JFE Advantech's AAQ-RINKO data processing software to generate vertical profiles. The dataset includes only the data collected during the descent from the surface to the seabed, with the turbidity data used to determine the time of bottom contact and exclude data points immediately before touchdown. Data processing was performed at 0.5 m intervals with a layer thickness of ±0.1 m. Data collection is still ongoing, with continued measurements planned for the future. | |
